@ovais Try running npm install --global --production windows-build-tools then try installing the CLI again. The previous command installs the C++ compilers that node-gyp needs. Windows by default does not have these installed and unfortunately this is just a quirk of working with nodejs on windows.
https://www.npmjs.com/package/windows-build-tools

[ghost]

Same error here. Tried different things. Gave up for the moment.

Windows 7
Node: v6.6.0
npm: 3.10.8

I read in another post that it should not be a requirement to install windows-build-tools, which also installs python 2.7.11 and takes foverer to finish the installation (i did it anyway, but didnt help).

Looking at the log and for what i can understand, execsync v1.0.2 fails to compile native extensions and because of that falls back to node-gyp, which requires windows-build-tools for Windows.
Is this correct?

[spillai98]

@splintercode Any way around for MAC users ?
using- Mac X El Capitan ( Version - 10.11. 3)

[adiachenko]

I can confirm that running npm install --global --production windows-build-tools WILL NOT fix this.

[Code-Bear]

I am getting the same errors on my Windows 10 install; looks like it can't find zopfli and then attempts to use python, which isn't installed.

[jcgomeztg]

i had same problem and noticed that angular-cli requires npm 3.x.x to be installed, after updating npm it could be installed npm install npm -g

[lekova]

I'm following the instructions in Upgrade from Beta.10 to Beta.14 trying to migrate to angular-cli@latest, running on Windows 10. I have deleted node_modules, tmp and dist, upgraded the npm version, run the uninstall, cache clean and install, and I'm getting an error:

[filipesilva]

@ovais as @jcgomeztg mentioned, Angular CLI needs npm 3. The errors you are getting (npm ERR! peerinvalid) are due to npm 2.

@lekova there was a bug with beta.15 I believe, that gave you that message. Try beta.16 and if the problem persists please open a new issue.

[luismanuelmansilla]

I has this problem too.. I use this to fixed -
Update Nodejs to version 4.
update NPM to latest -> npm install npm@latest -g
-> npm remove -g angular-cli
-> npm cache clean
and them install angular-cli -> npm install -g angular-cli

[Chembeti]

I had the same issue and after following luismanuelmansilla suggestions, I could install it. I have verified the installation with the commands "ng new" and "ng serve".

[joe-vella]

With "npm install -g angular-cli", new projects get angular release candidate bits and no modules. When I try "npm install -g angular-cli@latest" I get the same issues listed above. I am also on Window 10; I did try installing the windows-build-tools. I also tried "npm install npm -g" as suggested to only have that blow up too. I am currently at npm 3.0.0 and node 4.6.1.

[joe-vella]

SUCCESS! I ran "npm install npm@latest -g" which worked; I am now at npm 3.10.9. I then ran "npm install angular-cli@latest" which also, finally, worked and installed angular-cli 1.0.0-beta.18. I can now create a new project (at the correct angular2 version) and run it.

[grantmarch]

@joe-vella 's solution worked for me

[SatishMHiremath]

I have faced and fixed this issue relates node-sass and python error.Try installing latest angular cli command with the steps below

Set the system variable path as well:
C:\Users\windowsusername\AppData\Roaming\npm

C:\Users\windowsusername\AppData\Roaming\npm\node_modules@angular\cli\bin;

C:\Program Files\nodejs;

Then start using angular cli command prompt using:
angular client project folder path>npm install -g @angular/cli@latest

angular client project folder path>npm install -g node-gyp
